对5例颞下颌关节（TMJ）标本进行关节造影和X线电影摄影。结果发现，颞下颌关节发出咔哒声时，关节盘和髁突的快速运动以及髁突路径的隆起都与之相关，尸检标本中的咔哒声和运动似乎与颞下颌关节发出咔哒声的患者相似。四个关节在前突过程中出现了咔嗒声，但除非在之前的再关节中出现了晚期咔嗒声，否则不会发生这种情况。在这四个关节中，椎间盘随着咔嗒声而向与髁突相反的方向移动。结果表明，髁突，无论是在前伸和reversed.In第五关节，在髁突路径与点击相关的隆起在同一位置在前伸和reversed.In后脊的椎间盘滑动相关。关节盘与髁突运动协调，并可能发生滑脱。
Arthrography in combination with cineradiography was performed on five temporomandibular joint (TMJ) autopsy specimens with clicking. Clicking was found to be associated with rapid movement of disc and condyle and with a bulge in the condylar path. Clicking and movement in autopsy specimens appeared to be similar to that in patients with TMJ clicking. Four joints demonstrated clicking during protrusion, but this did not occur unless preceded by clicking late during a previous retrusion. In these four joints the disc moved in the opposite direction to the condyle in association with clicking. The findings indicated that the condyle, both at protrusion and retrusion, slipped over the posterior ridge of the disc in association with clicking forming the bulge in the condylar path. In the fifth joint, bulges in the condylar path associated with clicking were registered in the same location both during protrusion and retrusion. In this joint the disc and condyle moved coordinately and were possibly slipping ove...
